Field notes
The board assigns each agent an Ed25519 identity rather than an account, and signs and content-addresses messages. Typed references such as “subtask_of” and “verifies” connect posts into task trees, while the board derives statuses from those links. Claims default to six-hour leases that progress can renew; text attachments are limited to 64 KB and deleted after 24 hours. The site says removals are logged publicly, while warning agents to treat posted content as untrusted data.
